Polyester fleece 120 g/m² – Roll 0.15 × 50 m – Reinforcing fleece for roof waterproofing

Extra strong reinforcing fleece for long-lasting liquid waterproofing – tested, tear-resistant, durable.

The Polyester fleece 120 g/m² in 15 cm roll width is a high-quality reinforcing and special fleece Made from 99 % polyester, developed for professional sealing work with Liquid plastic, polyurethane and bitumen systems.

With a certified Tensile strength of up to 12.6 kN/m (DIN EN ISO 10319 – SGS test report no. QDIN2411002250PL01_EN) this nonwoven fabric offers maximum stability, elasticity and durability – even under high mechanical stress.

The microperforated structure enables uniform penetration with sealing materials and ensures optimal adhesion as well as a homogeneous sealing layer.
Additionally, the fleece sewn with polyester threads, which further increases the tear resistance.

Thanks to its narrow width, this variant is particularly suitable for precise detail sealing, where controlled work and material-efficient processing are crucial.

What width is suitable for my project?

• 15 cm roll width – ideal for transitions, inside and outside corners, pipe penetrations and precise detail work (current selection)

• 25 cm roll width – ideal for larger connections, parapets and transitions with increased safety margin

• 35 cm roll width – ideal for roof drains, gullies, fans, aerators and heavily stressed connection areas

• 50 cm roll width – Ideal for full-surface reinforcement of flat roofs, terraces, and usable roof areas. When applied over a large area, cracks, transitions, and detail areas are automatically reinforced.

Frequently Asked Questions (FAQ)

Can I also use the fleece with PU liquid plastic?
✅ Yes, it is compatible with bitumen, PU and other liquid waterproofing systems.. This Reinforcing fleece Works perfectly in all common systems.

Do I need to cut the fleece?
✅ Yes, it can easily be cut to size with scissors or a cutter.

How wide should the overlap be?
✅ We recommend an overlap of 5–10 cm.

Is the product UV-resistant?
✅ The fleece is intended for installation under sealing systems and should be covered in case of direct UV exposure.

Can the fleece be processed at sub-zero temperatures?
✅ Yes, the fleece itself is frost-resistant. The crucial factor is that the sealing material used is suitable for low temperatures.

How should the polyester fleece be stored?
✅ Store in a dry place, protected from UV light and ideally in a well-ventilated room.

How long does the polyester fleece last in a sealant?
✅ When applied correctly, it significantly extends the service life of the sealing system, as it distributes stresses evenly and prevents cracking.
